1.3 Putting into operation

1.3.1 Selecting or changing the location

The correct location is crucial to the accuracy of the weighing results!

Major geographicallocation changes

The manufacturer adjusts each scale to the local gravity conditions (GEO value). Inthe event of major geographical location changes, this setting must be adjusted by aservice technician. Certified scales must also be recertified observing the national cer-tification regulations. These steps are not necessary for scales with an internal cali-bration weight.

Adding/subtracting

Clear key

Keys 0 ... 9 and decimal point

Numerical keys for entering weight values, identifications ...

Key Function

➜ Select a stable, vibration-free and if possible a horizontal location.

The ground must be able to safely bear the weight of the fully loaded scale.

Observe the following environmental conditions:

• No direct sunlight

• No strong drafts

• No excessive temperature fluctuations

Aligning the scale

Only scales that have been aligned precisely horizontally provide accurate weighing results.

➜ Turn the adjustable feet of the scale until the spirit level’s air bubble is inside the inner circle.

10 User manual 22013182B 05/08


1.3.2 Connecting the power supply

CAUTION!

Before connecting the scale to the mains, check whether the voltage value printed onthe rating plate corresponds with the local mains voltage. ▲ Never connect the device if the voltage value printed on the rating plate is different

to the local mains voltage.

➜ Plug the mains plug into the socket.

After connection, the device performs a self-test. When the zero display appears,the device is ready to weigh.

➜ Calibrate the device in order to obtain the greatest possible precision, seeSection 4.3.2.

Note The storage battery is also suitable for permanent mains operation.

➜ In order to obtain the full nominal capacity we recommend that you discharge thestorage battery at regular intervals (approx. every 4 weeks) through normaloperation.

Scales with a built-in battery can work independently from the mains for approxi-mately 30 hours in normal operation. A prerequisite for this is that the backgroundlighting is switched off and that no peripheral devices are connected.

The device automatically switches to battery operation as soon as the mains supplyis interrupted. When the mains supply is restored, the device automatically switchesback to mains operation.

The battery symbol indicates the present charging level of the battery. 1 segment cor-responds to approx. 25 % capacity. When the symbol flashes the battery must becharged (min. 4 hours). The charging period is extended if work is continued duringcharging. The battery is protected against overcharging.

The charging time of the storage battery amounts to approx. 6 hours. If the devicecontinues to be operated during the charging process, the charging time is extended.The storage battery has a service life of approx. 1,000 charging/discharging cycles.

The compact scales BBA442 / BBK442 have a total of 100 memory locations for fre-quently used tare values, average piece weights, target weights and target quantities.In the factory setting, the memory locations 41 to 80 are reserved for average pieceweights. The saved average piece weights are also preserved when the scale isswitched off.

3.9.1 Saving average piece weights

1. Determine the average piece weight in one of the ways described earlier.

2. Enter the memory location number (factory setting: 41 ... 80) and keep pressed until the confirmation appears in the display, e.g. APW.41.

Note If an average piece weight had already been saved under the selected memory loca-tion, the message rEPLACE appears in the display.

• To save the new average piece weight, press . The old average piece weight is overwritten.

3.10.3 Counting in to target quantities

1. Place the empty container on the scale and tare.

2. Specify a reference.


The counting-in process can be followed in the graphic display. The 50 % markingis on the far left here, so that more display segments are available for precise fillingbetween 50 % and 100 %.

As long as the lower tolerance is not reached, the minus tolerance mark is dis-played.

If the counted-in number of pieces is within the defined tolerance, the mark OK isvisible and a short beep sounds if activated in the menu.

3.11 Counting with two scales

For piece counting, it is possible to connect a second scale or weighing platform, e.g.a floor scale for counting a large number of pieces via the optional analog secondscale interface.

The necessary settings for the application and interface parameters are described inthe Sections 4.4.1, 4.6.1 and 4.6.5.

Limit for activation of the I/O relay box. The value to be entered is the percentage proportion of the lower tolerance of the target weight/target quantity.

Checking the SP.Tol-- is carried out with the gross weight, for SP.Tol- with the net weight.

SP.Tol- is dependent on SP.Tol--; in other words, if SP.Tol-- has not yet been reached, the SP.Tol- output will not go active.

If both setpoints are used, the SP.Tol-- must be less than SP.Tol-.

5.1 SICS interface commands

The compact scales BBA442 / BBK442 support the command set MT-SICS (METTLERTOLEDO Standard Interface Command Set). With SICS commands, it is possible toconfigure, query and operate the scales from a PC. SICS commands are divided upinto various levels.

5.1.1 Available SICS commands

In the case of Levels 0 and 1, these are commands which, if implemented, willfunction identically with all METTLER TOLEDO scales or weighing terminals.

In addition there are also further interface commands which apply either to the entireproduct series or to the particular application level. This and further information on theMT-SICS command set may be found in the MT-SICS Manual (Order Number 22 011459 or at www.mt.com) or be obtained by request from your METTLER TOLEDOcustomer service representative.

Command Meaning

LEVEL 0 @ Reset the scale

I0 Inquiry of all available SICS commands

I1 Inquiry of SICS level and SICS versions

I2 Inquiry of scale data

I3 Inquiry of scale software version

I4 Inquiry of serial number

I6 Inquiry of weighing parameters

S Send stable weight value

SI Send weight value immediately

SIR Send weight value repeatedly

Z Zero the scale

ZI Zero immediately

LEVEL 1 D Write text into display

DW Weight display

K Keyboard check

SR Send and repeat stable weight value

5.1.2 Requirements for communication between scale and PC

• The scale must be connected to the RS232, RS485, USB or Ethernet interface of a PC with a suitable cable.

• The interface of the scale must be set to "Dialog" mode, see Section 4.6.1.

• A terminal progam must be available on the PC, e.g. HyperTerminal.

• The communication parameters baud rate and parity must be set in the terminal program and on the scale to the same values, see Section 4.6.3.

5.1.3 Notes on network operation via the optional interface RS422/485

Up to 32 scales can be networked with the optional RS422/485 interface. In networkoperation, the scales must be addressed from the computer before commands can besent and weighing results received.

8.2 FCC

This equipment has been tested and found to comply with the limits for a Class A dig-ital device, pursuant to both Part 15 of the FCC Rules and the radio interference regu-lations of the Canadian Department of Communications. These limits are designed toprovide a reasonable protection against harmful interference when the equipment isoperated in a commercial environment. This equipment generates, uses and can radi-ate radio frequency energy and, if not installed and used in accordance with the usermanual, may cause harmful interference to radio communications. Operation of thisequipment in a residential area is likely to cause harmful interference, in which casethe user will be required to correct the interference at his own expense.

Cet appareil a été testé et s’est avéré conforme aux limites prévues pour les appareilsnumériques de class A et à la partie 15 des règlements FCC et à la réglementation desradio-Interférences du Canadian Department of Communications. Ces limites sontdestinées à fournir une protection adéquate contre les interférences néfastes lorsquel’appareil est utilisé dans un environnement commercial. Cet appareil génère, utilizeet peut radier une énergie à fréquence radioélectrique; il est en outre susceptibled’engendrer des interférences avec les communications radio, s’il n’est pas installé etutilisé conformément aux instructions du mode d’emploi. L’utilisation de cet appareildans les zones résidentielles peut causer interférences néfastes, auquel casl’exploitant sera amené à prendre les dispositions utiles pour palier aux interférence àses propres frais.
